AMC7637

www.DataSheet4U.com AMC7637 www.addmtek.com DESCRIPTION The AMC7637 is an ultra low quiescent current, and low dropout regulator rated for 300mA output current. The low power consumption and high accuracy is achieved through CMOS technology and internal trimmed reference voltage. The AMC7637 consists of a high-precision voltage reference, error correction circuit, and a current limit output driver. The fast transient response is an outstanding feature for applications with various loads.
